THERMAL DATA

K Package:

Thermal Resistance-Junction to Case, θJC ................. 3.0°C/W

Thermal Resistance-Junction to Ambient, θJA ............... 35°C/W

R Package:

Thermal Resistance-Junction to Case, θJC ................. 5.0°C/W

Thermal Resistance-Junction to Ambient, θJA .............. 40°C/W

T Package:

Thermal Resistance-Junction to Case, θJC .................. 15°C/W

Thermal Resistance-Junction to Ambient, θJA ............ 120°C/W

IG Package:

Thermal Resistance-Junction to Case, θJC ................. 3.5°C/W

Thermal Resistance-Junction to Ambient, θJA .............. 42°C/W

L Package:

Thermal Resistance-Junction to Case, θJC .................. 35°C/W

Thermal Resistance-Junction to Ambient, θJA ............ 120°C/W

Note A. Junction Temperature Calculation: TJ = TA + (PD x θJA).

Note B. The above numbers for θJC are maximums for the limiting

thermal resistance of the package in a standard mounting

configuration. The θJA numbers are meant to be guide-

lines for the thermal performance of the device/pc-board

system. All of the above assume no ambient airflow.

RECOMMENDED OPERATING CONDITIONS (Note 2)

Operating Junction Temperature Range:

SG140A/140 .................................................. -55°C to 150°C

Note 2. Range over which the device is functional.

CHARACTERISTIC CURVES

Note 3. Operation at high input voltages is dependent upon load current. When

load current is less than 5mA, output will rise out of regulation as input-

oiutput differential icreases beyond 30V. Note also from Figure 1, that

maximum load current is reduced at high voltages. The 50V input rating

of the SG140A series refers to ability to withstnd high line or transient

conditions without damage. Since the regulator's maximum current

capability is reduced, the output may fall out of regulation at high input

voltages under nominal loading.
